/* ==================== BUTTON VARIANT GUIDE ====================
   Four variants in use across the app:

   1. .btn-primary           Primary CTA — saturated brand-accent
                             with white text. One per page, attached to
                             the dominant action: form submit, "Call now",
                             "Start campaign", "Save".
   2. .btn-outline-secondary Secondary action — outlined neutral. Used
                             for "Back", "Cancel", "Discard",
                             "Test connection", "Preview".
   3. .btn-outline-danger    Destructive — outlined red. Used for
                             "Delete", "Cancel campaign", "Hang up",
                             "Erase".
   4. .btn-link              Tertiary / link-as-button. Used for in-row
                             actions that aren't primary ("Edit",
                             "Re-queue", "Research").

   Status-state actions (Pause/Resume/Retry) keep their semantic
   Bootstrap colour (warning / success / outline-warning).
